[Bug 901061] New: Boot from usb on a ASUS Transformer T100TA
http://bugzilla.opensuse.org/show_bug.cgi?id=901061 Bug ID: 901061 Summary: Boot from usb on a ASUS Transformer T100TA Classification: openSUSE Product: openSUSE Distribution Version: 13.2 RC 1 Hardware: x86-64 OS: Other Status: NEW Severity: Major Priority: P5 - None Component: Bootloader Assignee: jsrain@suse.com Reporter: gerald.maricau@gmail.com QA Contact: jsrain@suse.com Found By: --- Blocker: --- The problem is simple : I own a tablet : ASUS Transformer T100TA, but the Acer Aspire Switch 10 is also affected. (this bug concerning ubuntu : https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1341944) Symtom: I can't install OpenSuSE because of a specific component : UEFI is 32-bit, despite the Processor architecture 64bit. " Intel released a new Atom iteration (Bay Trail) in late 2013 and has indicated that they will continue to develop and release Atom CPUs due to consumer market demand. At the time of this filing there are a number of Atom-based tablets and compact laptops/netbooks being actively sold and marketed by major OEMs including Dell, HP, ASUS, and Acer. None of these devices have 64-bit UEFI firmware. It is also important to note that these Atom CPUs are 64-bit, but explicitly require a 32-bit UEFI bootloader. " We need a Grub2 32-bit EFI enabled for booting the installation process. Thanks a lot -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=901061 --- Comment #3 from Michael Chang <mchang@suse.com> --- I can try to enable 32-bit build but I don't have any machine with 32-bit UEFI to test. And our openQA need to check the availability for 32-bit UEFI testing, because for now only 64-bit OVMF can be used for testing. The other obstacle is UEFI secure boot, shim only provides 64-bit build and I'm not aware any plans on 32-bit support. We need to also check efi kernel boot stub for 32-bit to decided to go with linux or linuxefi command for booting linux kernel. If the decision is efi boot stub in order to keep our configuration consistent for 32 and 64bit, we need to fix linuxefi to be able to build and work on 32-bit. Currently we can only offer linux command to boot the kernel if without doing any changes to existing source and no secure boot support at all. -- You are receiving this mail because: You are on the CC list for the bug.

And if you make some ISO available, i can test it to see what's happen. Thanks in advance. Regards, -- You are receiving this mail because: You are on the CC list for the bug.
http://bugzilla.opensuse.org/show_bug.cgi?id=901061 --- Comment #5 from Michael Chang <mchang@suse.com> --- Hi Gerald, The grub2 has already enabled i386-efi build, but we are still far away from creating an installable DVD for openSUSE, this requires support from other people. 1. kiwi for creating the iso image, and has to use grub2 as default loader to replace the missing shim, and the grub config has to use linux not linuxefi for loading kernel (as linux command is intentionally removed from grub.efi to prevent from using it to load unsigned kernel to bypass secure boot checking). 2. The grub2 package has to add linux module back to 32-bit grub.efi .. 3. The YaST and Perl boot loader, add support grub2-efi on 32bit x86 efi platform and also without any secure boot stuff in it. Not sure whether autoyast has to change anything for it or not. -- You are receiving this mail because: You are on the CC list for the bug.

Do you agree? Thanks. -- You are receiving this mail because: You are on the CC list for the bug.

Honestly, I don't believe that we can fix this for 13.2, possibly with later release of such image. -- You are receiving this mail because: You are on the CC list for the bug.
